PI-Jukebox not responding to Adafruit Capacitive TFT display #8

Open mgeilich opened 7 years ago

mgeilich commented 7 years ago

When I run pi-jukebox - sudo python pi-jukebox.py - I can see the currently playing song (if mpd is playing one) in the jukebox on my TFT display, but the controls don't respond to my finger and I can't get to any of the secondary screens. The screen responds to touch otherwise, for example for scrolling a terminal window. Any ideas?

Same issue with the official 7" raspberry touchscreen display : the screen works perfectly under raspbian but I can't use it with Pi-jukebox. Going to take a look at the source code (but I'm not a python user)...

mgeilich commented 7 years ago

I think I found my issue with Pi-jukebox by trying some other front ends and creating test music libraries on the Pi’s SD card. I discovered 2 problems. First, WiFi is simply not fast enough to transfer data from a SAMBA mounted filesystem to keep music playing. When Pi-jukebox gets behind in playing it just freezes. The other is that the Pi itself isn’t fast enough to keep up with user input in Pi-jukebox. It catches some input, drops other input, and freezes up.

I don’t see how this project could possibly work with a Pi, Pi-jukebox, and a SAMBA-mounted filesystem over WiFi. But it would be nice if it did!

I'm just trying to get this working with sample music on the sd card, nor wifi neither lan connection to music. Found in the settings.py that a "call" was made to a /dev/input/touchscreen which does not exists on my pi, maybe this is a clue. Still seeking...

Installed tslib as mentioned here : http://www.impulseadventure.com/elec/rpi-install-tslib.html Successfully tested with i2cdetect but still no /dev/input/touchscreen. Got a /dev/input/event2 which is the touchscreen (tested by a cat and pointing finger on the display) but cannot find a way for "settings.py" to use this event2 device (after having changed in the code, of course...)

mgeilich commented 7 years ago

I have a /dev/input/touchscreen which is a link to /dev/input/event1.

Sined66 commented 7 years ago

Lucky you are ! Not such file for me and don't know how to have it created.

mgeilich commented 7 years ago

I can tell you how to do that, though I can't tell you why installing tslib didn't set it up automatically for you. Perhaps you didn't use 'sudo' on the install and part of it failed with permission problems? You might want to try installing again. But, if you just want to solve the immediate problem:

sudo ln -s /dev/input/event2 /dev/input/touchscreen

Already tested without success... Tried to test tslib (which is correctly installed) : 

pi@raspberrypi:/usr/local/lib $ ts_test
/dev/touchscreen/ucb1x00: No such file or directory
pi@raspberrypi:/usr/local/lib $ ts_print
ts_open: No such file or directory
pi@raspberrypi:/usr/local/lib $ ts_calibrate
ts_open: No such file or directory

Really lost, I am...

mgeilich commented 7 years ago

I get the same results as you to those commands yet my touchscreen works fine. Just not with pi-jukebox. Although sometimes sporadic input is received so I think configuration is OK, just not performance.

Put the mouse pointer 'on' in the code : it works (but crashing just a few lines further...).

Sined66 commented 7 years ago

Still debugging code in order to progress :-(

mgeilich commented 7 years ago

From my experience I am guessing that the code is functionally correct, but operates too slowly on the Pi to keep up with touch events. Perhaps if the python was compiled down to bytecode it might be more efficient? Try python -O -m py_compile ./*.py

Don't know, but when activating the mouse pointer, I can move it and select things from the touchscreen...

spgarbet commented 7 years ago

I'm having the same problem. I got all the ts_test tools working properly, but it still doesn't seem to work. I suspect something in the TS interface for capacitive touchscreens, possibly a configuration issue.

This resolved the issue: https://learn.adafruit.com/adafruit-pitft-28-inch-resistive-touchscreen-display-raspberry-pi/pitft-pygame-tips. It's a downgrade from 1.2.15-10+rpi1 to 1.2.15-5 for sdl
